Dipole moment gives an idea of the polar character of a covalent molecule. It is a vector quantity as it has a direction as well as magnitude. A molecule with `mu=0` is non- polar and with `mu ne 0` is polar.
If the dipole moment of `NF_3` is `0.80 xx 10^(-30)` Cm, then the dipole moment of `NH_3` is

A

`0.80 xx 10^(-30)` Cm

B

`1.2 xx 10^(-31)` Cm

C

`4.90 xx 10^(-30)` Cm

D

`0.7 xx 10^(-30)` Cm
